Install PowerPoint (PPTX)

The skills CLI copies the skill into the folder of each agent you pick (Claude Code, Codex, Cursor, Copilot, Gemini CLI, OpenCode, Windsurf...). Add -g for all projects. Needs Node.js 22.20+. docs

npx skills add anthropics/skills --skill pptx

This repo is a plugin marketplace. Inside Claude Code, add it and install the plugin that holds the skill (document-skills, example-skills, claude-api, academy-guide...), or copy only this skill into ~/.claude/skills. docs

/plugin marketplace add anthropics/skills
/plugin install <plugin>@anthropic-agent-skills

# or only this skill:
npx skills add anthropics/skills --skill pptx -a claude-code

Download the skill folder, zip it, then Customize > Skills > + > Create skill > Upload a skill. Code execution must be on (Settings > Capabilities). docs

git clone --depth 1 https://github.com/anthropics/skills.git /tmp/pptx-src
cp -r /tmp/pptx-src/skills/pptx ./pptx
zip -r pptx.zip pptx

Codex reads skills from .agents/skills in the repo or ~/.agents/skills. Type $ in Codex to use one. docs

npx skills add anthropics/skills --skill pptx -a codex

gh skill (GitHub CLI 2.90+, preview) installs it for Copilot in VS Code, the CLI and the cloud agent. Copilot also reads .github/skills and ~/.copilot/skills. docs

gh skill install anthropics/skills pptx

Cursor reads .cursor/skills, .agents/skills and ~/.cursor/skills (and .claude/skills). It does not install loose skills from a GitHub URL, so copy it in. docs

npx skills add anthropics/skills --skill pptx -a cursor

Installs from the GitHub repo; --path picks this skill out of the repo. Default scope is user (all projects). docs

gemini skills install https://github.com/anthropics/skills.git --path skills/pptx

OpenCode reads .opencode/skills, ~/.config/opencode/skills and the Claude and .agents folders. docs

npx skills add anthropics/skills --skill pptx -a opencode

Windsurf (now Devin Desktop) reads .devin/skills, .windsurf/skills and ~/.codeium/windsurf/skills. docs

npx skills add anthropics/skills --skill pptx -a windsurf

Works with

Claude Code, Claude.ai and Claude Desktop, Codex, GitHub Copilot, Cursor, Gemini CLI, OpenCode, Windsurf and other agents that read the open Agent Skills format.

Bundles 15 Python scripts the agent can run, so it needs Python on the machine. In the Claude apps, code execution must be on.
